Single control characters
Ignore. The ignore character is an octal 17 (hexadecimal 0F). This
character is deleted from the print line when not preceded by escape-
escape paired control characters. That is, the print character
preceding the ignore character, and the print character following the
ignore character, are printed adjacent to each other.
Paired control characters
The first character of all paired control characters is the escape
character, which is an octal 77 (hexadecimal 3F).
Escape-escape. This pair is an octal 7777 (hexadecimal 3F3F).
These characters are deleted (as in the single ignore character), and
the character following the pair is always printed. When the ignore
character is preceded by this pair of control characters, the pair is
deleted from the print line, and the ignore character is printed.
Escape-skip. This pair is an octal 77 followed by a 6-bit binary
10nnnn (hexadecimal 3F followed by an 8-bit binary 0010nnnn). The
escape-skip pair is deleted from the output print line and causes
spaces to be inserted into the output print line. The 8-bit binary
number, 0nnnn000 (i.e., the binary number nnnn, 0 nnnn 15),
multiplied by 8 is the number of spaces (0-120) to be inserted.
Escape-line feed. This pair is an octal 77 followed by a 6-bit binary
00xxxx (hexadecimal 3F followed by an 8-bit binary 0000xxxx). The
escape-line feed pair, when deleted from the output print line,
terminates the output print line and causes the paper to be fed xxxx
binary number of lines after printing (where 0 xxxx F). Characters
following this pair, but preceding the end of this logical record, are
ignored.
